Ancient Romans used a specific type of purple dye made from sea snails
Tyrian purple was an incredibly rare pigment harvested from the glands of predatory sea snails, becoming a legendary symbol of imperial power and extreme wealth in the Roman world.
Known as Tyrian purple, this vibrant dye was extracted from thousands of Murex sea snails to produce just a single gram of pigment. The labor-intensive process made the fabric more valuable than gold, leading Roman emperors to pass laws restricting its use to the highest levels of society.
